As of this moment Bert Randolph Sugar and Brian Kenny of ESPN ranks Manny at least in the top 20 ATG. If Pacman beats Mayweather where would you put Manny in your ATG list?

Thanks.

Taking everything into consideration, probably about 6th for me... here are some of my pics - NOT IN ORDER (although top 5 is about right imo)
